Description
Technical field
The present invention relates to and contain extractible beverage ingredient as the capsule of coffee for preparation in beverage preparing machine.
Background technology
Disposable drink capsule is very universal because they can fast, convenient and the beverage of fresh trial test is provided cleanly.Therefore, some beverage capsule system proposes to extract coffee liquid from the coffee ingredient curing and grind be contained in capsule, and this capsule is opened under pressure when the water of q.s incapsulates.More particularly, before the output face of capsule is opened, in capsule, the pressure of liquid increases, and therefore forms good extraction quality.
Fully interacting between the coffee such as ground for making extractible beverage ingredient and hot water, wishing the release of the beverage delayed through outlet side.There is many different solutions.Especially, as described in EP0512470B1, Nespresso
capsule system is based on following principle, that is, the extraction face of capsule is torn against the protruding component of the capsule holder in beverage preparing machine and recessed element.When reaching rupture stress, extraction face is torn at the position of protruding component and/or recessed element, to make liquid such as coffee extract solution discharge at a certain direct draught after extracting coffee.EP0512468B1 also illustrate that a kind of capsule being suitable for this extraction process and equipment.
There are other for the internal pressure of the liquid because of injection exporting the method providing one or more aperture in wall, as related to (outside) punctured element outside capsule.
Also there is such capsule, described capsule comprises the output wall with prefabricated aperture, that is, open under the effect of liquid under the pressure of this aperture not in capsule.But most time, the location of aperture in output wall, quantity and size configurations become to produce negligible back-pressure, and this back-pressure only causes capsule mesolow to raise.Therefore, produce in capsule and transferred out the liquid as soap of poor extraction by it, such as " limpid " coffee.
Summary of the invention
The present invention is intended to solve the problem and proposes a solution, for the interaction providing better water-batching in capsule (bowl cup), be provided with prefabricated aperture during milking to provide the capsule of the pressure of rising in capsule in particular for exporting wall at it.
For this reason, the present invention relates to a kind of capsule for preparing beverage in beverage preparing machine, this capsule comprises body and exports wall (conveying wall), described body and output wall form the room containing extractible beverage ingredient, described output wall comprises at least one outlet, and wherein this output wall comprises internal layer and skin, and described internal layer comprises at least one first aperture, described skin comprises at least one second aperture
Wherein, the first aperture and the second aperture extend on the axial direction of capsule,
Wherein, ground floor and the second layer are adjacent, or ground floor and the second layer are at a distance of limited gap, and when there is gap, there is provided a kind of maze-type structure, this maze-type structure extends laterally across beverage flow paths in the gap between described first and second apertures.
Term " axial direction " relates to longitudinal axis of symmetry of capsule, and in use this axis is corresponding with the principal direction of the flow path through room." horizontal direction " relates to the direction extended in the plane relative to described longitudinal axis orthogonal or tilt a little (that is, being less than 45 °).
So-called " adjacent " refers to that described layer directly contacts, or along at least 75% 0.3mm of being not more than apart (when capsule is not subject to the pressure effect of inner side liquid) of their total surfaces.
Term " aperture " refers to be arranged on and exports in wall for any aperture allowing beverage to leave capsule.Described aperture can be implemented in output wall.Therefore export wall and can comprise one or more aperture.Aperture also can before preparing beverage or period by machinery or fluid method formed.Such as, one or more aperture can be formed by piercing through when capsule inserts in beverage preparing machine or cut, or form one or more aperture due to mechanical stress or the result of other stress that provided by liquid, gas pressure, heat, laser and combination thereof.Therefore, aperture can not be specialized before use capsule, but can occur when using capsule.
In preferred embodiment, the second aperture being biased relative to the first aperture in a lateral direction at capsule.As a result, export before wall leaving, the flowing of beverage such as coffee liquid extract is forced to advance and non-immediate is advanced in path vertically along the transverse path between two-layer, therefore makes advancing of beverage slow down.
In a kind of mode, the path between the first aperture and/or the second aperture is sealing.Sealing can realize in any suitable manner.Sealing can be realized by internal layer and/or skin itself or pass through additional layer-such as slotting intermediate sealing layer-realization between the two layers.
In a kind of mode, the flow path between the first and second apertures during milking can be opened by being applied to the internal pressure exported on wall.In a kind of mode, flow path is closed by the sealing (such as, leafing district) existed between internal layer and skin between inner orifice and outer aperture.Especially, flow path is closed by closed orifices.By described aperture, but by low thickness film or by the adhesive phase covering aperture, it can be weakened in advance.Therefore, described aperture by any suitable mode such as leafing (delamination, peel off), break, from Kaifeng such as perforation.
In a further mode of operation, the flow path between the first aperture and the second aperture is opened, and does not namely close or blow-by.This flow path by current-limiting apparatus such as flow channel in any way axially and/or hinder in a lateral direction.These current-limiting apparatus are placed between the first aperture of two layers and the second aperture.

Detailed description of the invention
The capsule 1A of first embodiment of the invention shown in Fig. 1,1A, 2 and 3.This capsule 1A comprise export wall 3 and circular section from supporting type cup-shaped body 2, this cup-shaped body 2 have for the top closed of injection water in capsule, frustroconical side wall 4, stretch out and end at the edge 5 of the end 6 rolled.As mentioned above, this body can be made with aluminium, plastics, paper, the material utilizing agricultural resource such as cornstarch (preferably having plasticizer) to obtain and combination thereof.This body can be harder, and with box lunch, it can not be subsided by during the blade punctures of coffee making machine device; This blade provides through the opening of capsule for water filling.This cup-shaped body limits a Room 8, and beverage ingredient is contained in this room, the coffee preferably curing and grind.The consumption of the coffee curing and grind can change according to the type of coffee (ristretto, espresso or lungo).Usually, the amount of dress coffee is in the chamber between 4.5 grams to 7 grams.Ground coffee is generally a place of production of Arabica (Arabica) and/or Robusta (Robusta) ground coffee or the mixture of Different sources.It should be noted that described body can take other difformity and configuration.Such as, it can be assembled together by different walls and make, but not makes cup shell.
As being shown specifically in Figure 1A, exporting wall 3 and being formed by respectively as the ground floor of internal layer 9 and outer 10 and the second layer.These two layers are contiguous to be placed, and only seals along their periphery potted line 15.
In first method, these two layers, at interface 11 place, in the flow path especially between the first aperture and the second aperture, there is no any being tightly connected.Preferably, ground floor 9 is by being located at multiple small size aperture 12 in its thickness and through liquid.Aperture 12 forms the aperture (pore) through this layer, and the diameter of this aperture is preferably lower than the average diameter (D of the coffee particles be contained in room 8
4,3).Described aperture is preferably distributed in ground floor 9, is the whole surface (Fig. 3) of this layer substantially to ensure that coffee extract solution can flow through.This guarantee can not form priority flow path in the batching layer of indoor, but all extractible beverage particles (such as, coffee particles) are all soaked suitably by liquid.
Second (outward) layer 10 is also made by aperture 13 permeation liquid.Second aperture 13 forms the outlet for carrying beverage of capsule.Therefore, each aperture 13 of the second layer arranges along axis A, and this axis A is arranged essentially parallel to the longitudinal axes L of capsule.The quantity in the second aperture 13 can be different with size from the quantity in the first aperture 12 with size.Preferably, skin provides the back-pressure higher than ground floor.Especially, the second layer 10 has the aperture number fewer than ground floor 9, but single aperture has larger diameter.In a word, the open surface area in the skin formed by aperture 13 is less than the open surface area in the internal layer formed by aperture 12.In the mode that another kind is possible, the outer field open surface area formed by aperture 13 is greater than the open surface area of the internal layer formed by aperture 12.
As shown in Figure 1A, by making described two layers arrange this output wall along their surface contact, to make layer 9,10 (produce fluid pressure in capsule before) adjacent one another are, and the second aperture 13 is biased relative to the first aperture 12.So-called " being biased " refers to that the axis A in aperture 13 does not aim at the axis B in any aperture 12.As shown in Figure 3, the first aperture 12 is laid through internal layer and distributes in such region, and described region is different from the region comprised through the second aperture 13 of the second layer.
Exporting wall 3 can insert and be sealed in the annular recess 14 of body, and this recess 14 is such as obtained by the step shape part of sidewall 4, as shown in fig. 1.Alternatively, wall 3 can be sealed on flange form edge 5.Alternative dispensing means is that ground floor 9 is sealed to recess 14, and is sealed on flange form edge 5 by the second layer 10.Especially, these two layers can in the resistance to periphery both seals (Fig. 3) of tearing of their peripheral region.Therefore, skin 10 during milking entirely can not remain from capsule dismounting and at least be connected with internal layer 9 as kept securely at potted line 15 in some region.
Fig. 1,1A and 2 the second embodiment in, the flow path between the aperture 12 of internal layer and outer field aperture 13 is closed by seal interface or sealing 11.For this reason, ground floor 9 and the second layer 10 link together by sealing 11, and arrange along the axis A relative to each aperture 13 into about the sealing plane P of 90 ° of orientations.In fact, sealing is closed for the flow path of liquid from the first aperture, aperture 12 to the second 13.
When hermetic unit is made for and the pressure when enough liquid is applied to it and/or is applied on the second layer 10 after by the first aperture 12, can break or leafing in sealing portion.Sealing can by being added in can the material of hot melt or adhesive make, as thin diaphragm seal (such as, PE, EVA etc.) between described two layers.Diaphragm seal can be very thin, such as, only have several microns.Sealing portion also can be the integral part of layer 9,10, so as to be formed as by heat sealing the rupturable joint that obtains.Such as, these two layers are by such as using hot-rolling or forcing press lamination two permeable thin slices and producing under heat and pressure.Middle fusible film may be needed, to obtain rupturable sealing between the two sheets.Then cut by layered product, to form circular output wall, this circle exports wall energy and is sealed on the body 2 of capsule.It should be pointed out that flow path carries out closing or sealing individually through seal orifice 12 and/or aperture 13 when also can not form bonding between internal layer 9 and outer 10.Then by the pressure of liquid in capsule the aperture of sealing opened and/or break a seal.
Fig. 2 illustrates when standing the extraction pressure of the coffee liquid in capsule, exports the situation of wall.Capsule is inserted in apparatus for producing beverages usually, the equipment as described in EP0512470B1.This equipment comprises capsule holder 16, and capsule is supported and is pressed on described retainer 16.Capsule holder 16 has a series of protruding component 17 as two-stage truncated cone pyramid and recessed element or passage 18.Described passage communicates with each other, to form the collection network of liquid extract.Little aperture 19 is set in the bottom of recessed element 18, for the output duct (not shown) making liquid extract can flow to this equipment through capsule holder.When the perforation by being provided by blade 7 fills water in the room of capsule, the liquid that solid coffee batching is progressively filled this room soaks, until produce pressure in the chamber.Interaction between pressurized hot water and coffee particles forms coffee-extract; This liquid extract is finally forced through the aperture 12 of ground floor 9.Along with the rising of pressure in capsule, the second layer 10 often outwards-namely against capsule holder 16-distortion.The region 20 be positioned at above recessed element 18 of lower floor 10 is often out of shape more than the region 21 of being supported by protruding component 17.Because the resistance of ground floor 9 pairs of pressure is less, its distortion is less than the second layer 10 in proportion.This discrepant distortion exporting wall 3 causes the generation in the restricted region 22 for flowing through the liquid between described two layers.But, because aperture 12,13 is biased mutually at least partially, so advance along zigzag path, until flow out the second (outward) layer and aperture 13 in liquid stream is forced between two layers 9,10 this restricted region 22.In addition, restricted tortuous flow is such as formed in the region that protruding component is formed by the pressure on capsule holder by stopping, these two layers keep in touch in this region.As a result, the release of liquid stream is not straight but very tortuous and restricted, to keep certain pressure in chamber interior.After stopping injects hot water in capsule, because the distortion of the second layer is preferably permanent deformation to keep the flow path between aperture 12,13 fully to open, so capsule still can evacuation of liquid.
Fig. 4 proposes the modification of the output wall of the capsule of Fig. 1-3.Except exporting the method for designing of wall, this capsule is identical with capsule 1A or similar.Especially, internal layer 9 and outer 10 are optionally sealed, to form the beverage flow restrictive openings 50 between the second aperture 12 and the first aperture 13.Aperture 12 in internal layer 9 can be arranged in the regional area 70 of this layer.Outer field aperture 13 is arranged in this outer field region 71, and this region 71 is biased relative to the region 70 in the aperture 12 of internal layer in the axial direction.More particularly, when these two layers are assembled into formation output wall, the region 70 for inner openings 12 superposes with outer field imperforated region 73.Equally, superpose with the imperforated region 72 of internal layer 9 for the region 71 of outer aperture 13.Opening 50 is in the horizontal relative to directional drilling.More particularly, the sealing 51 connecting internal layer 9 and outer 10 is designed to be limited in a lateral direction towards the beverage flow paths of exit aperture 13.
More particularly, sealing 51 defines flow restrictive openings 50, such as to form the passage between the non sealed regions 52 of each layer and sealing area 51.Therefore, opening 50 is formed by the unencapsulated adjacent part of each layer, and export wall in a lateral direction-namely along the plane P-extension of Figure 1A.The resistance of sealing should be enough to the pressure of opposing beverage and avoids leafing or break, and therefore ensures the control of the size to flow restrictive openings.
Pass output wall for making beverage and leave capsule, beverage must via the first opening 12 by internal layer 9, to enter unencapsulated region 52-this non sealed regions do not comprise any through aperture in skin, beverage is forced to change direction thus, and advance in restricted region 22 between the two layers in the horizontal, until it flows through the opening 50 of horizontal orientation, and again change direction (that is, forwarding axial direction to) with the second aperture 13 by being located in skin.As a result, for beverage stream provides tortuous and restricted flow path in output wall, this flow path contributes to the barometric gradient maintained during drinks extraction in capsule.
It should be noted that to arrange discontinuous sealing between the two layers to replace continuous print sealing 51.In addition, each opening 50 can obtain by rigid insert or delimit, and described rigid insert seals between the two layers, as little pipe section, steel tendon, corrugation plastic part etc.
Fig. 5 and 6 illustrates another embodiment of the present invention, and wherein capsule 1B comprises cup-shaped body 2 and exports wall 30, and this cup-shaped body 2 has the room 8 for assembling material, and this output wall 30 is for closing this room.Export wall to be formed by internal layer 31 and outer 32, described internal layer and skin are opened by maze-type structure 36,37 points, provide restricted zigzag path for by there is small―gap suture 42 between the two layers.Gap between two plane layers 31,32 has little thickness, and this thickness is preferably less than 1.5mm, is most preferably less than 1.0mm, such as, between 0.2mm to 1mm.
Internal layer 31 is rigid plastic elements, and it comprises planar wall 35 with holes and bump 36,37, described bump 36,37 outwardly plane layer 32 direction give prominence to.Wall 35 with holes comprises multiple aperture 38, and described aperture 38 is enough little coffee particles to be remained on the inside (such as, orifice diameter is less than 150 microns) of room 8.In the center 39 of the ground floor 31 delimited at the bump 37 by bosom, this wall is without any aperture.Bump can be shaped and be arranged to concentric ring.In bump 36,37, form little transverse opening 60,62, described transverse opening is provided for the restricted flow passage of beverage flow paths.Such as, each bump has single flow restrictive openings, flows to reach this portion, so that the road finding it to flow out for pressure beverage.In addition, each opening can be in 180 ° and be placed on each annular section, as shown in Figure 6.Preferably, opening 61,62 has very little cross section, and this cross section is enough to produce barometric gradient in capsule.Such as, this cross section (size) is 0.25mm
2to 2.5mm
2.
Certainly, the output wall of the capsule 1B of Fig. 5 and 6 also can comprise annular section such as part 37 and the single flow restrictive openings such as opening 62 of single protuberance, can omit the annular section of the second protuberance in said case.In addition, the shape of the part of protuberance is unrestricted, but preferably they will provide labyrinth, and described labyrinth can form the flow restrictive openings of limited quantity.
As apparent in figure 6, these two layers can at the free end of bump 36,37, optionally being sealed (being shown in broken lines) at potted line 33,34 place of layer 32, for forming the output wall connected, and avoiding flow restrictive openings may be walked around by beverage.By being sealed by described layer, can ensure that the beverage making by force to enter gap is through flow restrictive openings 60,62.
It should be noted that the horizontal flow restrictive openings of the output wall of any one in above-mentioned capsule 1A, 1B can by connecting the breachable seal sealing of described two layers before using capsule.The seal is by the pressure of liquid in capsule or destroyed by mechanical mechanism.
In addition, when there is gap, maze-type structure realizes by the independently plug-in unit be placed between internal layer and skin.
In addition, export wall and can partly or be formed entirely in body self, such as, a part for the bottom of forming body or whole bottom.Such as, body can be that wherein internal layer or outer field cup-shaped member are formed on bottom.
In addition, capsule can have the injection wall of the opening not needing to utilize blade punctures.
Finally, can arrange and the extra play exporting wall and be associated, the airtight layer of such as protectiveness, this airtight layer covers outer and can remove before use capsule.
